Batch payroll and deductions

We recently switched to direct deposit.   And now the deductions are calculating when I don't want them to.  We have an Account Receivable as a deduction for if an employee owes the company money for a purchase.   I do not want TAX, CPP, or EI taken off for than deduction.  I have put the deduction in the employee profile and  I have UNCHECKED the tick boxes in the employee profile, but it is calculating them anyway when I batch the payroll.
